Abstract: A rigid raft is provided for a gas turbine engine. The raft has an electrical system and/or a fluid system embedded in the material of the raft. The raft further has one or more first mounts for mounting the raft to the gas turbine engine, and one or more second mounts for mounting a gas turbine engine component to the raft. The raft further has one or more tethers which extend between respective first and second mounts and are embedded in the material of the raft.

Abstract: An electrical raft assembly for a gas turbine engine is provided. The raft assembly comprises a rigid electrical raft formed of a rigid material that includes an electrical system comprising electrical conductors embedded in the rigid material. The raft assembly further comprises an engine component that is mounted to the electrical raft. The electrical raft includes one or more integral cooling passages which guide a coolant fluid through the raft to cool the engine component.

Abstract: A rigid electrical raft has electrical conductors embedded in a rigid material. The electrical conductors transmit electrical signals through the rigid electrical raft, which may form part of an electrical system of a gas turbine engine. The rigid electrical raft also has electrical heating elements embedded therein. The electrical heating elements provide heat which may be used, for example, to prevent condensation and/or ice build-up and/or to raise the temperature of electrical components to be within a desired range.

Abstract: An electrical raft 200 comprising electrical conductors 252 embedded in a rigid material are provided to a gas turbine engine. The raft 200 is used to transport electrical signals (which may be, for example power and/or control signals) around a gas turbine engine. The electrical raft 200 has an electrical connector 700 embedded therein which is used to connect the electrical raft to an electrical unit, such as an EEC of a gas turbine engine The electrical connector 700 is resiliently biased so as to ensure a reliable electrical connection.

Abstract: An electrical raft (200) is provided that has electrical conductors (252) embedded in a rigid material (220). The electrical raft is provided with an electrical connector (700). The electrical connector (700) is mounted in the electrical raft (200) at a mounting angle (730). The mounting angle is set such that the electrical conductors (252) can be connected to the electrical connector without having to turn through an angle or a radius of curvature that would subject them to excessive bending stress. Similarly, the mounting angle means that any conductors (766) that may be connected to the electrical connector (700) do not have to turn through an angle or a radius of curvature that would subject them to excessive bending stress. Furthermore, mounting the electrical connector (700) at the mounting angle (730) may allow the assembled electrical raft (200) to be more compact.

Abstract: An electrical raft 200 is provided that has electrical conductors 252 embedded in a rigid material 220. The electrical raft 200 may have other embedded components, such as embedded fluid pipes 210. The electrical raft 200 is provided with a raft map 400 that indicates the location and/or path of components embedded in the electrical raft 200. The raft map 400 can be used to identify the positions of the embedded components, and may also be provided with active elements, such as LEDs, which may be used to indicate an operating state of the systems/components embedded in the electrical raft 200. The raft map 400 may be useful in assembly, repair and fault diagnosis, for example.

Abstract: A rigid electrical panel and a method of manufacturing a rigid electrical panel is provided with a fire protection layer on at least one side. The fire protection layer comprises fibers and an intumescent material. The rigid electrical panel comprises electrical conductors embedded in a rigid organic matrix composite. In the event of a fire, the fire protection layer protects the embedded electrical conductors, and any other features or components carried by the electrical panel.

Abstract: An electrical assembly including electrical raft having electrical conductors embedded in a rigid material is provided. The electrical assembly has an electrically conductive screen layer. The electrically conductive screen layer provides electromagnetic protection to the electrical conductors. The electrically conductive screen layer is electrically connected to a mounting fixture, which in turn may be electrically connected to an apparatus on which the electrical assembly may be mounted. The electrical raft is used to transport electrical signals (which may be, for example power and/or control signals), for example around a gas turbine engine.
